VALVE ATTACHMENT.

To all whom it may concern Be it known that 1, JOHN E. CARROLL, acitizen of the Unitecl States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, haveinvented new and usefulImprovements in a Valve Attachment, of which the following is aspecification.

My invention relates to new and useful improvements in a valveattachment, and

has for its primary object to provide such a device that may be readilyand quickly placed upon or removed from a valve, such as, for instance,a tire valve and includes means for connect-ion with some object such asan air pump or other tire inflating device so located as to be readilyaccessible when the device is attached to a valve which is practicallyinaccessible.

vide a structure of this character having a chamber for registrationwith the reduced externally threaded end of thevalve and [having meanscoacting with one of the flats of the valve stem to prevent rotation ofthe attachment when in place.

Another object of the invention is to provide a screw having slidingengagement with the body of the attachment and threaded engagement withthe inner threaded portion of the valve stem to hold the attachment inplace, said screw having a passageway through'its inner end for ingressof a substance or gas such as air to the valve.

A further'object of the invention is to provide a valve attachment whichmight be termed a goose neck having means for temporary connection withthe outer end of a valve and further provided with an outwardlyprojecting tubular arm for connection with an object such as'a tireinflating device, said arm being so positioned as to extend somedistance from the valve in order that easy access may be had to saidarm.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically'designated by 5 the claims.

In order that those skilled in the art to which this inventionappertains, m'ay'understand how tomake and use the same, I will describeits construction in detail, re

Another object of the invention is to pro- :ferring by numerals totheaccompanying drawing formlng a part of this application, In which i Fig.1, is a. fragmentary sectional view of an automobile wheel and. tireshowing my improvement attached'toa tire valve.

Fig. 2, is an enlarged fragmentary'sectional side elevation of the;tire'valve and the attachment thereon.

Fig. 3, is a section at the line 3-3501 Fig. 2. l

Fig.4, is a sectionat the line l4 of Fig. V

In carrying out my invention as here embodied, 2 represents anautomobile wheel here shown as one of the disk type because of-thepeculiar adaptability of the attachment to wheels of this class and 3 isa tire carrying the tire valve 4. A

The tire valve includes a stem..5 which is externally threaded and hastwo oppositely disposed flats 0r unthreaded flat faces 6 as well as areduced outer end 7 internally and externally threaded.

The valve attachment includes a body 8 having alongitudinal boretherethrough of two different diameters to form a chamber 9, forregistration with the reduced outer end of the valve, and acommunicating screw receiving hole 10 and both the recess and hole areunthreaded or smooth bored. Projecting laterally from one side of thebodyis a tubular arm 11' having an externallythreaded outerrend asindicated at 12 and the passageway 13 throughthis arm communicates withthe bore and more particularly with the screw receiving hole 10 in thebody 8. 1

A lip 14 depends from one side only of thebody 8 and is adapted toengage one of the flatfaces 6 of the valve when thebody is placed overthe outer end of said valve with said reduced end in the recess 9. Thedifference between the diameters of the recess 9 and theholelO producesa shoulder 15 which is adaptedto engage the extreme outer end of thevalve and. if found desirable a suitable packing or gasket 16 maybeinterposed between said shoulder and the end of the valve. I

A screw 17 consisting of ahead 18 and a stem 19, threaded adjacent itsinner end only, passes through the hole 10 for threaded engagement withthe intern-a1 threadsof the valve so that when the head of said screwengages the outer end ofthe body the latter will be drawn firmly "downupon the end of the valve and there held in place. This screw has acircumferential groove 20 formed 'to the rear of the threaded portion orbetween said threaded portion and the screw head so that when the partsare properly positioned said groove will lie inthe same plane as oralign with, the inner end of the passageway 13 in order to communicatewith said passageway, while a bore '21 is formed :inthe stemol the screwfrom its inner end to a point in the region'of the roove 20 where it hasan inlet .22'from the side of the screw thereby forming a. commay berevolved until the head thereof entire valve.

gages the outer end otthebody Sjto firmly :attach said .body temporarilyto the tire valve. When this has been done the groove 20 will .be inalignment with the passageway 13so that a 'communicationis formedbetween the arm :11 and the interior of the At the same time the lip 14will project a suflicient distance to engage one of .the'flat faces 6and thereby prevent rotation of the .body during placement of the screw.i

When the parts are in position as herein described and as shown in :Fig.1, the outer threaded end of the arm 11 "is some distance from the valveand is therefore away fronr the ordinary obstructions, such as the partsof a wheel adjacent its .tire valve,-so that an air pump orother'tireinfiating device may be readily connected to the arm offltheattachment. c

Of course I do not wish to be limited to the exact details ofconstruction as herein shown as these may be .varied"within the limitsof the appended claims without vdefpartin from thespirit of myinvention.

Having thus :fully described my" invention, whatl claim as new andusefulis 1. The combination with atire valve having an external fiat face'andan internal ,thread,yof an attachment for connection to said tirevalv'e,said1 attachment comprising a *body having a recess registeringwith the outer end otthe tire valve, and -,a-l1p projecting from thebody and engaging ,the flat face of the tire valve tor the -,pur posespecified. i e
